--- title: Explained: AdBlue in a Diesel Tank Skelmorlie canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/skelmorlie-north-ayrshire/ location: Skelmorlie county: North Ayrshire latitude: 55.867710 longitude: -4.890080 service: AdBlue in a Diesel Tank updated: 2026-10-27 --- # AdBlue in a Diesel Tank in Skelmorlie: How It Occurs and How to Stop It AdBlue already in the diesel tank? In that case put this page aside a moment, keep the ignition and motor off, then ring 0333 366 0103. Normally, if the motor has not run, it is emptied and fully rinsed where your vehicle is in Skelmorlie. The rest of this page covers why it occurs and how to ensure it doesn't — handy if you are reading ahead of time. ## AdBlue in a diesel motor: two tanks, two fillers Not one liquid but two: that is how many modern diesels near Skelmorlie and Inverkip carry, with diesel feeding your motor. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Each tank has its own filler. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Diesel goes in at each forecourt call-out, again and again. Rarely topped up, AdBlue normally goes in from a bottle, poured by someone who has to stop and think what filler to use. It's in the gap that the mistake lives. ## How does AdBlue in your diesel tank occur around Skelmorlie? It's hardly ever carelessness. Three things tend to line up. Haste follows from the warning. The car warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Montgomerie Terrace, or on the way home in the car park outside Eglinton Bar. Then your car is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand hits for the cap it would have used on the old one. Nothing halts the pour once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Upper Skelmorlie or the middle of Skelmorlie: it takes the same few seconds either way. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a driveway in Innellan or a forecourt around Skelmorlie, check these. They take a couple of seconds. - Position can mislead; the cap does not. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel caps usually do not. - Check the size: the smaller neck is, on plenty of vehicles, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of cars say there which fuel goes where. - The handbook. If your filler isn't by your diesel cap, it's in the boot or under the bonnet, and the handbook says which. - The previous driver will know. Check as you pick up a rental or company car — from Wemyss Bay's car park, say — rather than when the warning appears. ## Topping up AdBlue without it reaching your diesel tank For the day the light comes on — wherever it is in North Ayrshire — a simple routine to follow. - Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Long Hill. - Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap works — after you have found your filler and read it. - The diesel cap remains on. Where both sit under a flap, make sure it's shut before lifting the bottle. - Finish once your tank is topped up or the bottle is empty; before that, tip slowly using the built-in spout. - Shut the cap, then look again — confirm the diesel filler stayed closed throughout. After that, start the vehicle. Find during the second or third step that AdBlue went in the diesel filler? That's where you stop. Don't carry on to stage five. ## Already put AdBlue in your diesel tank around Skelmorlie? The short order of things, beginning with no starting your motor. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from. Ask the staff to help roll the vehicle clear of the petrol pump if you are at a forecourt — the Gulf, the another forecourt nearby or somewhere else. Leave it where it is if you're on your own driveway in Skelmorlie. If your motor has already run, stop as soon as it is safe then switch off. The next exit means the place to come off when you're on the M8, under 15 miles from Skelmorlie. Distance matters — a quick hop across Skelmorlie makes a smaller job than heading under 50 miles to Glasgow — so say roughly how far it went. ## Our arrival in Skelmorlie, and what happens next Wherever the car has stopped, whether outside the local primary school, beside Skelmorlie & Wemyss Bay Parish Church or on your own drive, our van travels to it. Both the work and our quote rest on three replies — which fluid, which quantity, and if it has run — so our technicians ask. The price comes on the call, ahead of any van leaving. Your system is then purged thoroughly, once the tank is drained. Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of that clears away by itself. That is why it counts more. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Your engine is fired up next and tested to be sure it runs properly, all before our engineers head off. Most jobs are finished in roughly half an hour once we get there, provided your engine hasn't run — and the pumps our engineers use are fine on a live forecourt yet quiet after dark outside a house. Payment happens on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer's report and a VAT invoice. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way. ## About Skelmorlie, briefly Skelmorlie is a coastal village in North Ayrshire, situated on the eastern shore of the Firth of Clyde, with Upper Skelmorlie and Wemyss Bay nearby.
